KILOWATT-HOUR METER PULSE SENSOR

The utility model belongs to a measuring device in control technology, which aims at overcoming the problem that pulses can be generated easily by the existing kilowatt-hour meter pulse sensors when the rotating disk of the kilowatt-hour meter is at a slow rotary speed. The utility model adopts a sampling circuit with double photometer heads, the maintaining blocking circuit of pulsed signals, and also adopts a clock control oscillators for extending the service life of the photometer heads. The utility model has the advantages of accurate metering, no excessive generation of pulsed signals, long service life, simple structure and convenient generalization.
